IMPROVEMENT IN HAT-BLOCKS.

Specification forming part of Lett ers Patent No. 159,088, dated January26, 1875; application liled December 2, 1874.

To all whom it may concern:

Be it known that I, FRANCIS R. GOING, of Boston, in the county ofSuffolk and State of Massachusetts, have invented an Improvement inHat-Blocks, of which the following is a specification Y My inventionrelates to a holder or form for sustaining hats in pouncingmachines, andconsists in a hollow block constructed as hereinafter described.

In pouneing hats they are stretched over or on a block made of a solidpiece of wood. These blocks are carried at the top of a vertical shaft,which is rotated several times in one, and then in the opposite,direction, a reciprocating rack engaging a toothed gear on the verticalshaft. This shaft is turned very rapidly, and its motion is reversedvery quickly, and consequently the machine has to be very strong, andespecially so as the momentum of the shaft, owing to the heavy woodenblock, is very great, and the strain on the machine and shaft is alsovery great when the motion of the shaft is suddenly reversed. I obviateall this strain on the shaft, save power, and make a lighter and easierrunning machine than has been heretofore made.

Figure l is a side view of my invention, and Fig. 2 is a cross-section.

My block A, for the pouncing-machine, is made of a thick strong piece offelt, fashioned to conform to the shape of the hat to be pounced,whether round or oblong, and stili'- ened or hardened by glue or othersuitable hardening compound, and the outer side is preferably varnishedto make it smooth. The block A is made hollow, or as a shell, and hasfitted to it a bottom or end piece, B, bored to receive a flangedcollar, O, suitably attached by means of screws, and provided withagroove or spline itted to receive or lit a spline or groove on the topof the usual vertical shaft of the pouncing-maehine.

rThis hollow block, instead of being of felt, might be of leather-boardproperly hardened, of stift' paper, of woven material, ot' thin metal,or might be made as a thin shell of wood, the wood being in the shape ofveneers or solid, the block being sustained at bottom against inwardpressure by a bottom piece.

I claim- A hollow hat-block formed of a felt or paper shell and asuitable supportingbase, suhstantially as described.

In testimony whereof I have signed my name to this speciiication in thepresence ot' two subscribing witnesses.
